Estimating the term…
This invention is a fuel composition for use in internal combustion engines comprising a major amount of a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, and greater than 5% by weight based on the total composition of an oxygenate selected from the group consisting of a saturated, aliphatic monohydric alcohol having on an average from 8 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons, and mixtures of the alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5% by weight of oxygen. The oxygenate significantly reduces particulate emissions from the exhausts of diesel powered engines.
A fuel composition comprising a major amount of a base fuel having no more than 10% by weight of olefins and no more than 10% by weight of esters, and greater than 5% by weight based on the total composition of at least one oxygenate selected from the group consisting of saturated, aliphatic monohydric primary, secondary and tertiary alcohol and mixtures thereof having on an average from 8 to 20 carbon atoms, at least one mono- or poly-ketone or keto-monohydric aliphatic alcohol having on an average at 5 to 25 carbons, and mixtures of the aforesaid alcohol(s) and ketone(s), said oxygenate containing no other oxygen in its structure, the amount of the oxygenate in the composition being sufficient to provide the fuel composition with at least 0.5% by weight of oxygen.
